HORACE THURSTON, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO JOHN C. SCHOTTAND CHAS. H. SCHOTT, BOTH OF SAME PLACE.

SHOE-LACE-TPPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 373,865, datedNovember'zg, 1887.

Application filedSeptember 2, 1887. Serial No. 248,567. (No model.)

To all whom may concern:

Be it known that I, HORACE THuRsToN, residing in Providence, Providenceycounty,

Rhode Island, have invented an Improved' cords, Src., such as are usedfor shoes, corsets,

and the like, and also for pointing said tips.

The invention consists in the combination, with a grooved base,of twosliding plates earried in a suitable guide on the machine and placedface to face, each plate preferably having a specially hollowed end. Thehollowed ends of the plates are adapted to enter the recess in the baseand roll the tip-blank into a cylidnder and to fasten it upon the stringor cor v The invention also consists in the combination, with saidplates, of alever carried by the machine, which lever passes throughslots in the plates. Said slots are so arranged with relation to thelever that the plates will be moved together by the said lever, but atcertain times at different speeds, and then into the said recesstogether to roll the blank.

The invention also consists in the combination, with said base, of anick or recess on the edge of the tip-forming'groove and of a nick ont-he lower edge of one of the sliding plates,

which nicks are adapted to register when said plate is lowered into therecess.- By placing the end of a completed tip in the nick in the baseand lowering the said plate the end of the tip will be pointed by saidnicks and any projecting pieces cut off by the edge of tho plate.

The invention also consists in detaiis of construction and combinationsof parts, as will be more fully hereinafter set forth.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in whichl Figurel is aside view of atipping-machineconstructed according to my invention. Fig. 2 is a face view of thesame. Fig. 3 is a vertical cross-section through the sliding plates,their guide, and part of the base, the lever being broken off, showingsaid plates in the raised position, with the blank in the position itassumes before being rolled. Fig. 4 isa similar View to Fig. 3, showingthe sliding plates in the positions they assume before they enter therecess in the bed, the tip having been partly rolled. Fig. 5` isa Viewsimilar to Fig. 3, showing the sliding plates in the lowermost positionwithin the recess in the bed and the completed tip in position upon thestring. Fig. 6 is a vertical cross-section through the lower part of thesliding plates and part of the guide and base, showing the end ot atipin position to be pointed. Fig. 7 is a face view of one of theblanks. Fig. 8 is' a view showing the end of a string having a completedtip applied. Fig. 9 is an enlarged section of the parts that roll theblank.

A in the drawings represents the base of my improved tipping-machine.The base A is provided on its upper face with a transverse groove orrecess, c, preferably ofthe form Shown.

B D are two sliding plates adapted to lenter the recess a, and arrangedface to face, as shown. The plates B D are supported and slide in agrooved post, E,whicl1 projects from the base A. rlhe plates B and D areby preference provided with guide-slots forV receiving a pin or screw,b, which passes through said slots into the post E to hold the plates inposition; but other means may be used for this purpose, if desired. Thelower edge of each of the plates B and D is preferably hollowed out inthe forni approximating a quarter-circle, as shown at d e, so that whenthe lower edges of said plates are brought together, as in Fig. 5, thetwo hollows will together form a semicircle. The. upper parts of theplates B and D are provided with slots f g, respectively,which slots areadapted to register when the plates are in the position shown in Figs. 1and 5, and to be more or less out of line when in the positions shown inFigs. 8 and 4, for the purposes hereinafter stated.-

F is a lever which is pivoted to a lng, h, on the post E back of thesliding platesB and D. The lever Fk projects through the slots f g inthe plates B and D, as shown. By operating said lever the plates B and Dwill be reciprocated lengthwise, as hereinafter stated.

t is a nick or recess in the base A on the edge of the groove or recessa, as shown. j is a corresponding nick or recess on the lower edge ot'the sliding plate B, and it is arranged to register with the nick i whenthe grooved lower edge of the plate B enters the recess a.

This tippingmachine operates as follows: The lever F is first movedupward. This carries the plates B D substantially into the positionshownv in Fig. 3-that is,with their lower edges out of line and out ofthe groove c. A tip-blank, G, and a string or cord, m, are now passedinto the recess a, the lower slightlybent part of the tip-blank beingpreferably turned toward the front of the machine, as shown in Fig. 3.The upper edge of said blank G now rests against the sloping lower endofthe plate B. The lever F is now brought down to roll the tip and bearsupon the lower ends of the slotsfg, so as to move the two plates B Ddownward together at this time at nearly equal speed. During thisdescent of said plates the upper end of the blank G is conned betweenthe plates B D, so that it cannot drop backward or forward` This isshown in full lines in Fig. 3. As the lever F continues to descend, itnow moves the plate B a little faster than the plate D, this beingcaused by the part of the lever F over the edge of the slotf movingfaster than the inner part. This gradually brings the edges d e of thesaid plates into the position shown in Fig. 4. While the plates havebeen descending, as described, they have rolled the lower part of theblank partly around the string in the groove a., as shown in Fig. 4. Afurther downward movement of the lever causes the two slots f g toregister, as in Fig. 5. This brings the ends of the plates B D together,the grooves d e forming a semicircle, as in Figs. l and 5. A furtherdepression of the lever F now carries the two plates B D togetherfarther into the re cess a, completely rolling the blank aroundthestring. During all the time that t-he plates B and D are descendingthe blank G is being gradually rolled. The lever F is now raised and thetip on the string removed from the recess a. To form a point on the tip,the end of the rolled tip is placed in the niek i. (Sec Fig. 6.) Thelever F is now depressed to bring the plate B, with its nick j, downupon the tip. This jams the end ofthe tip between the nicks i and j,forming a point, and any projecting end of tip and string will be'cutoii" by the edge of the plate B. The plate D is not essential to thisoperation and could be dispensed with, if desired, the plate B aloneperforming the Work of pointing the tip, as it is not necessary to pushthe end of the tip far enough under the plates B D to be operated uponby the plate D. The plates B and D move when the lever F is operated,whether the plate B alone or both the plates are per forming a function.

Although I have shown in the drawings the ends d e ofthe plates B l)grooved, these ends could be flat or of other suitable shape for rollingthe tip in the groove a.

Having now described my invention,what I claim isl. In atipping-machine, the base A, hav ing the groove a, combined with thesliding plates B D, both adapted to enter the groove a to roll atip-blank, and with means for operating the plates B D, substantially asdescribed.

2. In a tipping-machine, the grooved base A, combined with the slidingplates B D, having grooved ends d e, which form a semicircle whenbrought together, and with the lever F, substantially as described.

3. The grooved baseA and sliding plates B D, combined with the lever F,adapted to move the plates B D at even and different speeds,substantially as described.

4. The grooved base A, combined with the grooved sliding plates B D,having slots fg, and with the lever F, adapted to pass through saidslots, said slots being arranged to register when the lever isdepressed, but to be out of line when the lever is raised, substantiallyas described.

5. The base A, having groove a and nick z', combined with the plate B,having nick j, and lever F, all arranged so that the nicksi' and] willregister when the plate Bentcrs the recess a for the purpose of pointinga tip and cutting the same, substantially as described.

6. The combination of the grooved base A, having niek t', with thereciprocating plates B D, having grooved ends d e and nick j, allarranged for turning atip-blank and for pointing and cutting it olf,substantially as specied.
